Question

What is the concentration of ecdysteroids in late l3 drosophila larvae?

Answer 1

Answer:

Ecdysone, and not just 20E, precisely regulates metamorphic timing in Drosophila.

Ecdysone, and not just 20E, precisely regulates metamorphic timing in Drosophila.•

Ecdysone, and not just 20E, precisely regulates metamorphic timing in Drosophila.•Ecdysone causes acceleration of metamorphic timing and reduced body size.

Ecdysone, and not just 20E, precisely regulates metamorphic timing in Drosophila.•Ecdysone causes acceleration of metamorphic timing and reduced body size.•Metamorphic timing is determined by antagonistic interaction of ecdysone and JH.
